毎日カラム値をリセットする

Question

私のカラムは毎日1000から開始する必要があります。新しいエントリごとに、この番号は1ずつ増加します。翌日には、再び1000に戻ります。これをどうすればいいのですか？

CREATE TABLE [dbo].[GN_GnNm_Generate_Number_T](
    [GnNm_Code] [varchar](50) NOT NULL, 
    [GnNm_Pad_With] [varchar](3) NOT NULL, 
    [GnNm_No_Of_Times] [varchar](6) NOT NULL,

Answer 2

と仮定テーブル名は 'TABLE_1'

自動増分列名が 'ID'

日付列名が 'ENTRYDATE'（TABLE_1は、このコラムを持っていると仮定）

DECLARE @NewId int = 0 

IF EXISTS (select * from Table_1 where EntryDate=GETDATE() and ID=1000) 
    @NewId = (select max(ID) from Table_1) + 1 
ELSE 
    @NewId = 1000 

INSERT INTO TABLE_1(ID,EntryDate) VALUES (@NewId,GETDATE())
